title: MRI appearance of a cerebral cavernous malformation in the caudate nucleus before and after chorea onset.
abstract: Movement disorders associated with cerebral cavernous malformations (CM) are seldom reported, and chorea, in particular, is rarely associated with a CM located in the caudate nucleus. Here we report a 78-year-old female patient with chorea, who presented with choreiform movements due to a CM in the contralateral caudate nucleus. A brain MRI was obtained and compared with that obtained before the onset of chorea. The new images did not reveal further extralesional hemorrhage from the CM when compared with the previous images. The choreiform movements showed spontaneous improvement and then disappeared completely. We reviewed previous reports of patients with chorea associated with a CM, and conclude that CM located in the caudate nucleus can cause chorea.
